Level Meter

NivuMaster Transmitter

Part No. NM5; NM6; NMA; NMB; NM9

For level measurement using ultrasonic sensors

For the supply of connected ultrasonic P-Series sensors, processing of signal data and indication of computed readings. Ideal or measurement and control in level and volume applications

  • Measurement of level, distance, volume, difference and flow
  • Alarm output in case of flooded sensor possible
  • Pump control saves energy and costs thanks to intelligent pump management
  • High measurement reliability through intelligent agitator avoidance
  • Connection of maintenance-free, Ex-protected ultrasonic sensors  
  • Up to 6 relays and galvanically isolated mA outputs
  • Easy echo analysis and setting of parameters using free PC software
  • Integrated emergency power switchover
  • Easy operation in dialog mode using back-lit graphic display

The NivuMaster series transmitters supply connected P-Series sensors, process measurement values and indicate readings. NivuMaster transmitters are ideally suitable for simple control tasks in level measurement applications. Flow measurements in open channel using a Venturi flume or Q/h-relations, on any kind of weir or discharge sills are possible without any problems.

NivuMaster is available with wall mount enclosure, as 19"-plugin or with panel mount enclosure.

The few parameters required for measuring can be entered easily on site in dialog mode thanks to the back-lit display and the integrated keypad.
Parameters can be evaluated using the free software “PC Software Suite” and the serial interface of the transmitter.
